Unable to distribute embedded python with torch-directml

[bcw222]

Description:

I have packed an embedded Python environment with torch-directml pre-installed to distribute for running Stable Diffusion on ComfyUI. It works on my develop host with NVIDIA GPU, but I encountered the following issues:

• On Windows 1809:
  I receive the following error when trying to import torch_directml_native:

  ImportError: DLL load failed while importing torch_directml_native: Unable to find the module
  

  I attempted to reinstall the torch-directml package using pip, but the issue persists.

• On newer versions of Windows (with Intel iGPU):
  The package runs, but when I attempt to run Stable Diffusion on ComfyUI, I encounter errors. The behavior is inconsistent across different machines, with some working as expected while others fail.

Steps to Reproduce:

1. Pack a embedded python with torch-directml and ComfyUI requirements.
2. Deploy the package on a machine expected to support torch-directml with Intel or AMD GPU.
3. Attempt to run Stable Diffusion on ComfyUI with torch-directml as usual.

Expected Behavior:

Stable Diffusion should run without errors.

Actual Behavior:

• On Windows 1809: DLL load failure when importing torch_directml_native.
• On newer versions of Windows: Inconsistent behavior when running Stable Diffusion, with errors occurring on some machines with Intel iGPUs.

Additional Information:

• The package works correctly on some machines with Intel iGPUs on newer Windows versions.
• I have tested with both the latest version of torch-directml and the most recent Intel graphics drivers.

Environment:

• OS: Windows 1809 (and newer versions)
• Python: Embedded version with torch-directml pre-installed
• GPU: Various machines with Intel or AMD GPU
• ComfyUI: Running Stable Diffusion models

Request:

Is there a known issue with torch-directml on certain versions of Windows? Are there any known workarounds for these issues to pack a standalone environment for offline usage, particularly regarding missing or incompatible DLLs or other dependencies?
